Sharpness at 45mm

Our sharpness tests were conducted using a 50-megapixel Fujifilm GFX 50S body mounted on a tripod. The camera's shutter release was also set on a timer-delay to avoid any possible camera shake. The test subject was shot using ambient lighting, hence some colour and contrast variation is to be expected between apertures.

Centre sharpness is impressively high throughout the entire aperture range, with peak performance between f/4-f/16. Corner sharpness is also excellent, again producing optimal sharpness at f/4-f/16.
